ISIS group threatens Facebook and Twitter CEOs

Frustrated by social networks' efforts to keep them at bay, the terrorist group ISIS has made direct threats against the CEOs of Facebook and Twitter.

In a 25-minute video dubbed "Flames of the Supporters" and posted on the Russian-based instant messaging service Telegram, the Sons Caliphate Army displayed photos of Facebook co-founder and CEO Mark Zuckerberg and Twitter CEO Jack Dorsey with digitally added bullet holes. Sons Caliphate Army is a purported hacking division of the Islamic State.
